I 10 the like.

An object of the invention is the provision of improved means for fastening a cantilever arm orhook to a support.

A more particular object of the invention 15 is the provision of an improved hook or sup- I port operable to be folded from a horizontal to a vertical positionwhen the hook or support is not in use.

Still another particular object of the invention is the provision of improved supporting means for a cantilever arm or the like which permits the arm to be folded downwardly when not in use and which is oper- W able by its own weight and the weight of the load carried thereby to lock the arm against collapse.

The invention has among its further objects the production of a device of the kind n, described, which is simple, convenient, durable, reliable, eflicient, and satisfactory for use wherever found applicable.

Many other-objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combi nation of parts herein shown and described, and more particularly pointed out in the claim.

Referring now to the drawings, the; nu meral l0 generally designates a' cantilever device embodying the principles of my invention. For this purpose the. cantilever device is shown as comprising an, arm 11 suitably fastened to a support 12. The support 12 may take the form of a block, a board or the wall of a room or ofa closet or the; like. .The arm 11 is hingedlytconne'cted to the support 12 about a horizontal axis by means of a plate 13." The plate 13 is fastened to thesup .port bya plurality of screws 14.

The plate 13 is provided with a forwardly extending projection or fold 15. The upper and lower walls, and front edge of the projection 15 forms a recess 16 in whicha pin 17 is mounted.

A pair of vertical slots 22, are symmetrically arrangedabout the verticalv centerline of the projections 15. The slots 22 are 'sutd ciently wide to insert therein a side web 25 of the cantilever arm 11. The side .webs 25 are connected atthei-r top by a curved portion 26. The webs 25 and the curved topportion 26 provide the arm 11 with aninverted U-shaped cross-section. It is obvioustha t one or any desired number of webs 25. may be provided. If two or more Webs 25 are provided, such webs can be connected at their bottom or in some. position intermediatev the top and bottom and the shape of the connecting portion need not. necessarily be curved.

The top portion 26 is shown curved to cooperate with hooks 29 of clothes hangers 28 or the like. he outer end 27 of the hook 11 is turned upwardly to preventthe possibility of the hooks 29 being pushed off of the'arm by accidental contact therewith.

Oppositely positioned, vertically "extending, aligned apertures 19 are formed in the side webs'25 adjacent the rear end ofthezarm 11. The device is assembled by inserting the webs 25 of theiarm 11 in the-corresponding vertical slots 22 in'the fold :15; andrthen inserting thepin 17 in the recess 16 and through the slots 19.15 The slots 19 are preferably made to closely fit and permit sliding of the pin 17 therein.

The position of the slots 19, relative to the end of the arm 11, is such that when the pin 17 is inserted in the slots with the arm 11 horizontal, the end of the arm abuts and thereby fits the front face of the hinged plate 13. The pin 17, after being inserted in the recess 16 and the slots 19, is fastened by forming indentations 18 in walls of the fold or projection 15. The rear end of the arm 11 is preferably made of greater depth than the forward portion of the arm in accordance with the principles of design of cantilevers in order to provide sufficient material towithstand the bending strain which increases towards the support of a cantilever beam.

The additional depth of the cantilever beam at its rear end permits the vertical slots 19 to have a greater depth than would otherwise be practicable. The ends of the slots 19 are curved and of the same radius as that of the pin 17 so that when the arm 11 is in the position shown in Fig. 1 there is full bearing on a semi-circumferential area of the pin. The end faces 21 of the webs 25 abut the front face of the plate when the arm 11 is horizontal as already described. The vertical por tion of the faces 11 lying opposite to and below the pin 17, in the position of the pin shown in Fig. 1, transmits the load thrust to the plate 13 with which the ends 21 contact. The lower ends of the slots 19 terminate near the lower edges of the side webs 25. The distance from the extreme lower end of the slots 19 is made the same as the distance from the inner bounding edges of the slots to the faces 21 forming the ends of the arm 11. The lower rear corners 20 of the webs 25 are curved, the radius of curvature being concentrio with the radius of the curved lower ends of the slots 19. The concentric curvature of the corners 20 and the lower ends of the slots 19 permits the arm 11 to be folded downwardly when the arm is in its uppermost horizontal position. By lifting the arm 11 upwardly until the pin 17 is positioned in the extreme lower ends of the slots 19, the weight of the arm 11 will cause the arm to take the vertical position shown in dotted lines in Fig. 2. It will be noted that the curvature of the corners 20 is such that the arm 11 cannot be folded downwardly except when the pin 17 is in the extreme lower ends of the slots 19. The weight of the arm 11 tends to retain the arm with the pin 17 positioned in the upper ends of the slots 19 in which position the arm cannot be folded. Any weight suspended from the arm 11 also tends to hold the arm 11 in the full line position of the drawings, wherein the arm is inoperable to collapse from horizontal to vertical position. This arrangement prevents the possibility of such arms or hooks collapsing by accidental contact therewith as frequently occurs when in use as a clothes hanger or the like.

The device is adapted not only for the sup port of clothes hangers, in wardrobes, closets or other constricted spaces, but may be utilized for many other purposes. For example a plurality of the spaced apart arms 11 can be used as a support for shelving which, when not in use, can be folded vertically to occupy a small amount of space.

Not only is the device adapted for the support of clothes hangers, shelving or the like, but it may be utilized for any other purpose wherein it is desirable to provide cantilever supports capable of being folded into vertical position when not in use.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is In a device of the kind described, a cantilever arm, a plate forming a support for the arm, said plate having a forwardly projecting member, said member having a horizontal recess therein and a plurality of spaced apart vertical slots opening into said recess, said arm comprising a plurality of spaced apart web members fixedly fastened together, the ends of said web members being each positioned in one of said slots, said web members each having an elongated slot formed therein adjacent its rear end face and in registry with said recess, a pin fixedly mounted in said recess and projecting through said elongated slots, said pin and elongated slots cooperating to cause the rear end faces of said web members to abut the plate when the arm is horizontal.

In witness whereof, I hereunto subscribe my name this 28th day of June, A. D. 1929.
